The Los Angeles Regional Transportation Management Center serves as the emergency command center for the Caltrans District 7, California Highway Patrol and Los Angeles County Metro and was designed to remain operational after a severe earthquake. This five-story, base-isolated building was built to allow emergency dispatchers to help manage freeway traffic and maximize roadway capacity, providing safer conditions for the public when traveling. This essential services facility was designed using performance-based engineering to maximize its optimal performance. The building is supported on 23 36-inch diameter rubber isolators, which allow it to move up to 24 inches relative to the ground. Seismic energy is dissipated through 300-kip fluid viscous dampers. The foundation consists of a mat foundation within a depressed “moat” which allows for building movement.
